This assignment is one which you yourself must complete as it involves an emotional and psychological response from you. Moreover, we editors at Enotes are certainly glad to accommodate you on information regarding single questions, but we do not compose essays for students.
Notwithstanding the limitations imposed, here is a suggestion that may assist you in your efforts.
Choose a novel or short story from what you have read that is on the literary canon for high school or that is a classic as it will provide you with a richness of style and plot that will give your analysis depth. Since most high school juniors in the U.S. study American Literature in their eleventh year, why not examine something written by Ernest Hemingway, F. Scott Fitzgerald, Stephen Crane, Jack London, Willaim Faulkner, or John Steinbeck? If you have not read any of their novels, each of these authors have excellent shorter works.
e.g. Steinbeck's novellas The Pearl and Of Mice and Men
Hemingway's "The Short Happy Life of Francis Macomber," "A Clean, Well-Lighted Place," "Fathers and Sons," "The Killers," "The Snows of Kiliminjaro," et. al.
Fitzgerald's "Babylon Revisited," "Winter Dreams," "Crazy Dreams," "Head and Shoulders" (ironically humorous), "The Ice Palace," et. al..
Stephen Crane's "The Open Boat"
Jack London's "To Build a Fire"
William Faulkner's "A Rose for Emily," "Barn Burning," and others
All of these works have summaries, analyses, critical essays, explanation of theme and style here on Enotes. (Simply type in the title in the window that has the red "Search" button. In addition, you can access many critical essays through the virtual library and Contemporary Literary Criticisms. While doing so takes some time, the exercise of researching criticisms is well worthwhile. Having read professional works, you will discover that you can branch off from some aspect of these criticisms and make your review your very own. So, read a work that you like, and put your heart into your efforts; for, you will attain rewarding results for having delved into a literary work youself. Happy reading!
